This is about the tenth film I've seen where a group of WW2 Allied troops stumble upon some secret Nazi experiment bunker that's using the occult or wacky science to create weapon-zombies. What slightly elevates this one above many of them is the fun design of the zombie/monster things. They're yer basic zombie walker types but with lots of whirly mechanical slicey death-bits added on. Kinda like an angry Ford Capri.
Anyway, if it's your sort of thing and you don't mind wobbly-cam then it's worth a go.
